Abstract
An exercise apparatus includes a base having a support stand upstanding therefrom. A pair of spaced apart foot rails each have a first end and opposing second end. The second end of each foot rail rests on the base of the frame. A pair of stroke rails each have a first end and an opposing second end. The first end of each stroke rail is slidably attached to the support stand of the frame while the second end of each stroke rail is hingedly attached to a corresponding foot rail. An axle of a crank is rotatably mounted to the support stand. A pair of crank arms each orthogonally project from the corresponding ends of the axle in opposing directions. Each remote end of the crank arm is rotatably mounted to a corresponding stroke rail between the ends thereof.
Claims34
An exercise apparatus comprising:
- (a) a frame configured for resting on a ground surface;
- (b) a pair of spaced apart foot rails each having a first end and an opposing second end, each foot rail being configured to receive a corresponding foot of a user;
- (c) a pair of stroke rails each having a first end and an opposing second end, the second end of each stroke rail being hingedly attached to the first end of a corresponding foot rail;
- (d) means for connecting each stroke rail to the frame such that linear reciprocating displacement of the first end of each stroke rail results in displacement of the second end of each stroke rail in a substantially elliptical path;
- and
- (e) means for selectively varying the size of the substantially elliptical path that the second end of each stroke rail travels.
An exercise apparatus comprising:
- (a) a frame configured for resting on a ground surface and having an support stand;
- (b) a pair of spaced apart foot rails each having a first end and an opposing second end, each foot rail being configured to receive a corresponding foot of a user;
- (c) a pair of stroke rails each having a first end and an opposing second end, the first end of each stroke rail being slidably attached to the support stand of the frame, the second end of each stroke rail being hingedly attached to the first end of a corresponding foot rail;
- and
- (d) means for connecting each stroke rail to the frame such that linear reciprocating displacement of the first end of each stroke rail results in displacement of the second end of each stroke rail in a substantially elliptical path.
An exercise apparatus comprising:
- (a) a frame configured for resting on a ground surface and having a support stand;
- (b) first and second crank arms rotatably mounted to the support stand of the frame, the crank arm rotating about a fixed axis;
- (c) first and second foot rails having a first end and an opposing second end, a portion of the first foot rail movably resting on the frame;
- (d) stroke means extending between the crank arms and the hingedly attached to said four rails & for rotating the end of the first foot rails in a substantially elliptical path when the crank arms are rotated in a circular path.
An exercise apparatus comprising:
- (a) a frame comprising a base configured for resting on a ground surface and an support stand;
- (b) a pair of spaced apart foot rails each having a first end and an opposing second end, a portion of each foot rail resting on the base of the frame;
- (c) a pair of adjustment arms each having a first end slidably attached to the support stand and an opposing second end;
- (d) a pair of stroke rails each having a first end and an opposing second end, the second end of each stroke rail being hingedly attached to the first end of a corresponding foot rail;
- and
- (e) means for adjustably attaching the second end of the adjustment arm to a corresponding stroke rail.
